There is an issue with LEDs. In spite of the low wattage, cooling is a problem. I saw some fittiings used in a commercial envitonment, and these had been specially designed to overcome that problem, but the colour, whilst ok for the environment selected, would not be good in an old carriage, having a bluish tinge. The old incandescent lamps usually are quite yellowy.

It will be interesting to see how the LED lighting matches up to the traditional light bulbs. Which reminds me of a light hearted observation about lights - lamps. This is about forum participation on changing the things. Sorry to those who have seen it before.

How many forum members does it take to change a light bulb?
1 to change the light bulb and to post that the light bulb has been changed
14 to share similar experiences of changing light bulbs and how the light bulb could have been changed differently
7 to caution about the dangers of changing light bulbs
1 to move it to the Lighting section
2 to argue then move it to the Electricals section
7 to point out spelling/grammar errors in posts about changing light bulbs
5 to flame the spell checkers
3 to correct spelling/grammar flames
6 to argue over whether it's "lightbulb" or "light bulb" ... another 6 to condemn those 6 as stupid
2 industry professionals to inform the group that the proper term is "lamp"
15 know-it-alls who claim they were in the industry, and that "light bulb" is perfectly correct
19 to post that this forum is not about light bulbs and to please take this discussion to a lightbulb forum
11 to defend the posting to this forum saying that we all use light bulbs and therefore the posts are relevant to this forum
36 to debate which method of changing light bulbs is superior, where to buy the best light bulbs, what brand of light bulbs work best for this technique and what brands are faulty
7 to post URL's where one can see examples of different light bulbs
4 to post that the URL's were posted incorrectly and then post the corrected URL's
3 to post about links they found from the URL's that are relevant to this group which makes light bulbs relevant to this group
13 to link all posts to date, quote them in their entirety including all headers and signatures, and add "Me too"
5 to post to the group that they will no longer post because they cannot handle the light bulb controversy
4 to say "didn't we go through this already a short ***e ago?"
13 to say "do a Google search on light bulbs before posting questions about light bulbs"
1 forum lurker to respond to the original post 6 months from now and start it all over again.

You often get an option between cool white and warm white - the cool white is the "native" state and therefore brighter, they do something to the warm white ones to make them more yellow which reduces the light output. There is a firm called Lightplanet that imports (supposedly) 60W incandescent equivalent LED bulb/lamp on either bayonet or screw fitting. They are pricey but they look like old style "lightbulb" bulbs so may be more appropriate in some settings where people would expect to see an old bulb fitting.

Dont know what LEDs you were looking at but cooling is not a problem in fact they run virtually cold. A lot of mobile discos, nightclubs bars etc are now using them and one of the selling points (apart from the 50000 hr life) is the lack of heat they give off. Where as the old fixtures that used halagon bulbs required the use of a fan onboard for cooling the LED lighting has no such requirement therefore (along with no cost for replacement bulbs) lowering the price of the lighting unit in the first place so would be interesting to hear in what application cooling was a problem as this seems at odds with one of the main reasons their use is becoming widespread in the entertainment industry.

Agree on the actual colour they give off be different though, definately a white LED is missing that lovely yellowish tinge of a traditional bulb.
